Greater Changhua onshore substations energised

Ørsted has announced the energisation of the 900 MW onshore substations for the Greater Changhua 1 & 2a offshore wind farms. Following first power in late April, the substations mark the completion of onshore construction.

Energization of the two onshore substations, located in Changhua Coastal Park, Tawian, was delivered via a close collaboration between Ørsted and Star Energy Corporation (SEC), a 100% subsidiary of Taiwan Cogeneration Corporation.

Christy Wang, General Manager of Ørsted in Taiwan, said: “For the past three years, our teams have worked closely with Star Energy and over a dozen of local subcontractors, to turn an area of desolate land into Taiwan’s first offshore wind transmission hub meeting international offshore wind QHSE standards. This is a great achievement for both our teams, Star Energy as well as the domestic sub-suppliers and contractors. It is also a testament to the successful combination of global offshore wind expertise and local experience.

“Moreover, the project serves as an excellent example of Ørsted’s efforts and dedication to cultivate a local supply chain. We are proud to see more than 80% of the Ørsted team and local contractors are from Taiwan, comprising around 1,000 people directly and indirectly involved in this project. The Greater Changhua 1 & 2a Offshore Wind Farms, the largest of its kind in Taiwan, have contributed to the development of a truly local supply chain and creating local jobs, as well as further strengthening Changhua as the green energy hub in Taiwan.”

With an investment of NTD 7 billion, this engineering, procurement and construction contract (EPC) scope includes two substations and a 3.7-kilometer culvert box that allows ventilation and protection of the cables.

Tsai Chin-Fa, Chairman of Star Energy, said: “The collaboration with Ørsted on the onshore substation and onshore transmission system was Star Energy’s first foray into the offshore industry, which was a critical decision to transform ourselves from inside out. Not only have we changed our mindset on QHSE, most importantly, we have also created partnerships with many local small and medium-sized enterprises, encouraging them to be part of Taiwan’s green energy transformation journey.”

Taiwanese suppliers participated in various scope of the EPC contract, from civil engineering, reactors, cable laying, equipment installation all the way to provision of air conditioning equipment.

Ørsted is currently constructing the Greater Changhua 1 and 2a offshore wind arrays which are located between 35 and 60 kilometres off the west coast of Changhua County, Taiwan. They will consist of 111 Siemens Gamesa SG 8.0-67 DD offshore wind turbines, each with a capacity of 8 MW. The wind farms will have a combined capacity of approximately 900 MW, which is expected to be enough to supply around one million Taiwanese households with green power.
